First time actually thinking about going into self-employment/contracting through an agency/own company.
Since I can see I have a lot to read through and a number of things to compare (plus a lot of people make a very good living by understanding this in detail), I don't necessarily hope for a step by step guide, but any advice would be appreciated.
It should be assumed we are talking about higher or additional tax band type income. I hoped it to be a discussion both about tax, NI and pension, summarizing what the most efficient type of setup would be.
My gut feeling is that establishing a chain of companies, with the end ownership in a tax haven, should be most efficient; with the UK subsidiary acting as your employer/agency.
